The Schedule referred to in these Letten Patent and making part 0f thesame.

. Be .it known that I, Osons VAN TAsssLn, of Na.- perville, in thecounty of Du Page, and State of Illinois, have invented a new and usefulImprovement in Bolt-Feeder; and I do hereby declare that the followingis a full, clear, and exa/ct description thereof, which will enableothers skilledin the art to make and use the same, reference being hadtothe accompanying drawings, forming part of this specification.

Figure 1 is a vertical longitudinal section of my improvedbolt-ieeder,taken through the line a: x, fig. 2. `Figure 2 4is a top view of thesame.

My invention# has for its object to furnish an improved device, by meansof which the i'lourvor iiieal is fed faster or slowerV to the bolt, as.maybe desired, and which shall, at the Sametime, be simple in construc'tion and easily operated; -and Y It consists in the cpnstruction andcombination o f the various paits, as hereinafter more fully described.

A represents the cylinder or spout, through which the tlour or meal isconducted to the bolt. y

In the lower end of the cylinder A is placed du apron or chute, B, bymeans oil which the flour is guided into the bolt. l

C is a `vert-ical shaft, passing up through the centre vof .thecylinderA, and revolving in and being supported by bearings, attached tothe frame-work that `supports the said cylinder A;

'.lo the lower end of the shaft() is attached a bevelgear wheel, D, intothe teeth of which mesh the teeth ofv the bevel-gear wheel E, attachedtothe shaft E, which is connected with and driven from thedrivingruechauism of the mill, by a pulley and band, or by otherwell-known and convenient means.

Through the upper end of the'shait C, passes a cross-bar, to which arepivoted, and upon which'rest two semicircular disks G, which form theauger or screw, by which .the flour is fed tothe bolt.

H is a lererwhich passes'in through a hole in the wow- I' 'side of thecylinder A5, and is .pivoted to thesaid cylinder.

The inner end of the leverHis'forked, and rides upon a groove in thecollar I, which slides up and down for a short distance upon the shaftO, and is connected with said shaft in such. a way as to be car` liedaroundwith it in its revolution. l

J are two rods, the lower ends of Awhich are pivoted'.

to the sliding collar I, and the upper ends of which are connected withthe wings or semicircular disks G, upon opposite sides ofthe rod, towhich` said disks are pivoted, so that when the collar I is raised, theopposite ends of said diskspor wings will be raised, to feed the iiourforward to theb'olt.- t

By this construction, by raisingthe collar 'I more or less, the pitch ofthe wings G will be adjusted, t-o feed theourforward faster orslower, asmay be ldesired. .If desired, the wings G may he rigidly attached to theshaft O, and the'feed be regulated by .adjusting y the speed at .whichthe shaft Gis driven.

Having thus described my invention,

I yclaim as new, and desire'. to secure `by `Letters Patent- 1. Thewings or semicircular disks Gand shaft O,

Avin combination withthe cylinder or spout, through which the tlour ormeal is conducted to the bolt, when said parts are constrnctedandoperated substantially as herein shown and described, and for thepurpose set forth.

2. rlhe combination of the lever H, sliding collar I,

connecting-rods J, pivoted wings or scmicircular disks G, and shaft G,with each other, and with the cylinder or spout, through which the ouror meal is conducted tothe bolt, substantially as herein shown anddescribed, and for the purpose set forth. n
